Hi, The following vulnerability was published for libapache2-mod-auth-openidc. CVE-2021-39191[0]: | mod_auth_openidc is an authentication/authorization module for the | Apache 2.x HTTP server that functions as an OpenID Connect Relying | Party, authenticating users against an OpenID Connect Provider. In | versions prior to 2.4.9.4, the 3rd-party init SSO functionality of | mod_auth_openidc was reported to be vulnerable to an open redirect | attack by supplying a crafted URL in the `target_link_uri` parameter. | A patch in version 2.4.9.4 made it so that the | `OIDCRedirectURLsAllowed` setting must be applied to the | `target_link_uri` parameter. There are no known workarounds aside from | upgrading to a patched version. If you fix the vulnerability please also make sure to include the CVE (Common Vulnerabilities & Exposures) id in your changelog entry.
